From a Facebook Post on LP Radicals by a (proclaimed) member of the audience for the taping earlier today:
Just came back from (the taping of) Ron Paul on Jay Leno. Ron Paul did not endorse anyone and said a third party run was unlikely. So the news? *SPOILER ALERT* He was kind of subtle about it, but he said he needed a rest for 2016. He did not say it was for Rand either. (I guess he’s not done yet. Yay!) That was the announcement, if any. It was amazing to see him. He was about 6 feet away from me at the very end before exiting stage left.
The program is due to be broadcast about 1 hour from now beginning in the eastern time zone.
